Also, there was a great need in 1863 for the new dynasty to distance themselves from the former degenerate, sterile and immoral former Oldenborg rulers.
Feelings don’t change facts. The House of Oldenburg is German in origin; in such houses one is a member of the house one’s father belonged (if of legitimate birth) going back as far as one can trace. “Changing” a house’s name only effectively creates a cadet branch.
>> The English Royal Family changed their dynastic name because of feelings.
Anyhow, if the Glückbsborgs have not been able to change their dynastic name, then there is a parallel with Queen Elisabeth of England who would not have to worry if her decendants would be Mountbatten-Winsor, they would be Sachsen-Coburg-Gotha-Schleswig-Holstein-Sønderborg-Glucksburg (or Sachsen-Coburg-Gotha-Oldenburg). And certainly NOT Saxe-Coburg, since that place is in Germany, and German at the time was much more widely spoken than English.
The Glücksburgs didn’t change their house name upon ascending the Danish throne. They already existed as a cadet branch of the House of Oldenburg. There was no decree to change their name. It was simply just a fact as being descended in a legitimate male line from the dukes of Glücksburg of the House of Oldenburg.
>>The Danish royal family never releases decrees or letters of patent. They "let it be known". Latest instance is Prince Henrik's different titles.
Elizabeth II is not Queen of England; she is Queen of the United Kingdom and fifteen other realms. Her descendants are members of the House of Windsor, their branch being a line of the House of Glücksburg, which is a branch of the House of Oldenburg. None of her descendants are Coburgs of the House of Wettin because none of their fathers are.
>>I use England by the same logic as you use Oldenburg. The majority of the world call her Queen England.
House names were not generally decreed because they happened as a matter of fact of male line descent and they automatically changed when the male line did.
>>House Names have changed a significant number of times thorughout history when the rulership was passed through the female line.
